Sorry, What I meant to really say is specs are not sufficient. Sure specs are important. But even with specs, without comprehensive conformance tests implementations will diverge. I work on the WebGL spec and tests based off the OpenGL ES spec and tests. Even though the OpenGL ES spec is long and detailed, every edge case for which there is no test is broken or different in one driver or another.
